Police are trying to work out how a twelve-year-old boy fell from a moving car in Mirrabooka overnight.
The incident occurred just after 10 pm Thursday night when a 16 year old boy was driving a red Volkswagen Golf hatchback along with two passengers along Cobbler Road.
It's understood one passenger, a 12 year old boy, was "car surfing" when he fell from the car near Northwood Drive, sustaining serious head injuries.
